It can do the initial installation such as claim AP to Org, assign/unassign AP, or place on map, etc., but cannot unclaim or remove the AP from the Org.

Question 2

All the access points (APs) on the site will obtain an IP address for the Management VLAN. You notice an additional IP address for each configured VLAN on the AP.

Which statement is correct in this scenario?

AThe AP is configured to support wireless mesh.

BThis behavior is enabled by default under the Site configuration.

CThe Local Status Page has been enabled in the AP setting under the Site configuration.

DThe AP MAC has a DHCP reservation.

Correct answer: C

According to the Mist documentation1, a Mist AP will pull a management IP address from the Native VLAN by default. However, if the Local Status Page is configured for the Site, all the site APs will pull their own IP address from the Management VLAN, but also addresses for each of the VLANs configured on the AP. This is because each AP creates a Switch Virtual Interface (SVI) for each VLAN on its eth0 interface.

The Local Status Page is a feature that allows you to access information about an AP's status and configuration through a web browser by connecting to its IP address2. This feature can be enabled or disabled at the site level under Site Settings > Access Points > Advanced Settings.

BListen to verify that the medium is free before transmitting.

CStations only transmit when polled by the access point.

DTransmit on a fixed schedule.

Correct answer: B

According to the IEEE 802.11 - Wikipedia document, one thing that 802.11 stations perform to help avoid collisions on the WLAN medium is to listen to verify that the medium is free before transmitting. This is part of the carrier-sense multiple access with collision avoidance (CSMA/CA) mechanism that 802.11 stations use to coordinate access to the shared medium.
